Linear diffuser Description, Areas of application and Benefits The SAL 35 slot diffuser is a linear diffuser with 35 mm-wide profiles. It comprises eccentric ABS cylinders that slide into extruded aluminum profiles mounted on a plenum. The SAL 35 is available in single or multiple slot versions depending on application and air quantity required. The components may be installed in a row, one beside the other, creating a linear slot of air diffusion. Areas of application - Comfort zones with average ceiling heights - Zones with high level of air mixing and low air velocity - Situations where the...

Linear diffuser Configuration and Method of operation Controlling the direction of airflow The SAL 35 linear slot diffuser is comprised of a profile of extruded aluminum (1) with an additional profile, narrow or wide (2), eccentric cylinders (3) sliding into the profile and revolving a full 3600, and a plenum (4) The eccentric cylinder (3), with optimized acoustics and aeraulics, has, on its axis, aside from multiple profiles directing the airstream (5), a reading and setting disk (6) on which alphanumerical characters are inscribed. The characters on this disk define and reproduce the cylinders...

Linear diffuser Selection the number of slots . Air flow V [m / h/m SAL] Important : In order to facilitate SAL selection, it is essential to calculate the total airflow rate for active lengths of 1 m. Requirements: 1- Airflow rate per metre of slot section 2- Number of slots n in cooling mode Solution: 1 Each slot of 1500 mm = 1.5 m length, Dividing then by 1.5 in order to find the airflow rate by meter of slot : 324 m³/h ÷1.5 = 256 m³/h/m Air Flow by meter of slot of SAL 35 V0 From diagram "Selection the number of slots", in a cooling mode, we note the number of slots : n = 3 Cooling only for...

Linear diffuser When all cylinders of the first slot are adjusted to 2 1 and those of the second slot to 6 5, this setting provides an air blast in two directions (divergent). The opposite diagrams show the relations between the eccentric cylinder's position and the air blast direction at the exit of the cylinder. BC/EF Diffuse AB/EF Diffuse BC/EF Diffuse Therefore, the airflow combinations are practically infinite. For the diffused mode, cylinders must be set according to applications illustrated in the diagrams 2 1 and 6 5 in alternating order. This setting produces a high induction airflow...
